Description
Hi, I'm running some performance comparisons between OpenBLAS and MKL for LU and eigen routines. I see that OpenBLAS tests with, for example, dgetrf and dsyevd, are about 3 times slower than MKL. These are multi-threaded tests ran on a Skylake machine.
I wonder if you have any benchmark results vs. MKL and if so how do they look like?
Thanks.

Research direction
Start by reproducing the multi-threaded dgetrf and dsyevd comparisons against MKL on a Skylake machine. Review any existing OpenBLAS benchmark results and document a like-for-like performance comparison, including the test conditions and observed differences.
